Lever arch file Biurfol A3 70 mm blue — model sek1490019

Biurfol lever arch file A3 70 mm in blue is designed for organising and storing A3-format documents, drawings and large-format papers. The folder features a 70 mm spine that accommodates multiple documents and a lever-operated locking mechanism that secures papers for upright shelving and easy retrieval. Its rigid cover provides stable support for stacking and long-term archiving in offices, studios and archives where A3 storage is required.

Advantages

The lever arch file offers a durable rigid cover and a reinforced spine that keeps contents flat and protected. The lever-operated mechanism allows quick opening and closing for efficient filing and removal of A3 sheets. A clear visible spine and reinforced edge reduce wear during frequent handling, while the 70 mm capacity supports a substantial volume of papers without deforming the folder.

• Archiving artwork, sketches and presentation materials
• Office filing for departments handling A3 paperwork

How to use

Open the lever mechanism to spread the rings and insert punched A3 documents onto the arch. Close the lever to lock papers in place and ensure the ring catches are fully engaged. For unpunched sheets, use compatible hole punches for A3 format before filing. Place the folder upright on a shelf or in a cabinet; the rigid cover maintains shape and supports stacking. Do not overfill beyond the 70 mm spine capacity to avoid stress on the mechanism and cover.

Usage recommendations

Store the lever arch file in a dry environment and avoid exposure to direct sunlight to maintain colour and material integrity. Label the spine clearly for fast identification and distribute heavy contents across multiple folders to preserve the folder's shape and the lever mechanism's function.
